Abstract

The motor and pump unit (14) includes a motor unit (16) and a pump unit (18). An outer housing (12) in two parts (20, 22) fits round the entire unit. At least one part of the motor and pump unit is coupled to the outer housing via a damping layer. This layer may be coupled to a fixing part attached to the outer housing, namely the fixing part by which the unit is itself attached to the vehicle.
